Jsf 2 不显示项目标签

使用f:selectItems在视图中显示列表时，不会显示itemLabel上的值。此外，无法获取itemValue上的id。 我只想在selectItems上显示itemLabel

但是，展示一下： ID=1，descripcao=Livro

而不是： 利夫罗

我做错了什么？有什么想法吗

我有一个f:selectItems，如下所示：

<h:panelGrid columns="2">

                <h:outputText value="TIPO:"/>
                <p:selectOneMenu value="#{publicacaoMB.publicacao.tipo}">
                    <f:selectItems value="#{tipoMB.listTipos}" var="tipo"
                                itemLabel="#{tipo.descricao}" itemValue="#{tipo.tipoId}"/>
                </p:selectOneMenu>
        </h:panelGrid>

和ManagedBean：

@ManagedBean
@SessionScoped
public class TipoMB extends ManagedBeanBasico implements Serializable{


    private static final long serialVersionUID = 2482494734070978599L;
    @ManagedProperty(name = "tipoFacade", value = "#{tipoFacade}")
    private TipoFacade tipoFacade;
    private List<Tipo> listTipos;
    private Tipo tipo;

public List<Tipo> getListTipos() {
        try {
            listTipos = tipoFacade.getTodosTipos();
        } catch (DAOException e) {
            e.printStackTrace();
        }
        return listTipos;

    }

还有一个正面：

public class TipoFacadeImpl implements TipoFacade, Serializable {


    private static final long serialVersionUID = -8560527136998650945L;
    @ManagedProperty(name="tipoDAO", value="#{tipoDAO}")
    private TipoDAO tipoDAO;
    private List<Tipo> listTipos;

public List<Tipo> getTodosTipos() throws DAOException {
        if(listTipos == null) {
            listTipos = tipoDAO.getTodosTipos();
        }
        return listTipos;
    }

还有一把刀：

public class TipoDAOImpl extends NamedParameterJdbcDaoSupport implements TipoDAO, Serializable {

    private static final long serialVersionUID = 8698127647660788120L;
    private SimpleJdbcInsert sji;
    @Value("#{queries.sql03}")
    private String sql03;

public List<Tipo> getTodosTipos() throws DAOException {
        try {
            RowMapper<Tipo> mapper = getRowMapper();
            return getJdbcTemplate().query(this.sql03, mapper);
        } catch (EmptyResultDataAccessException ex) {
            throw new DAOException("Não há registros na tabela de tipos.");
        } catch (DataAccessException e) {
            throw new DAOException(e.getMessage());
        }

    }

    private RowMapper<Tipo> getRowMapper() {
        RowMapper<Tipo> mapper = new RowMapper<Tipo>() {
            public Tipo mapRow(ResultSet rs, int rowNum) throws SQLException {
                Tipo t = new Tipo();
                t.setTipoId(rs.getInt("tipo_id"));
                t.setDescricao(rs.getString("descricao"));

                return t;
            }
        };
        return mapper;

只是一些注释：我想标准是使用itemValue={tipo}，然后使用一个转换器用于tipo搜索jsf转换器。另外，jsf中的getter方法中不应该有逻辑，我认为应该将getListTipos中的代码移动到带有@PostConstruct的init方法中，然后从getterIn返回listTipos。换句话说，getListTipos方法返回了一个没有descripao属性集的Tipo实体列表？或者您是否已经排除了该部分表单是原因？这个问题不清楚。JSF在这里只是模型的演示者。如果模型一开始就已经损坏，JSF做不了什么。@BalusC属性descripcao已设置。但是f:selectItems不会在itemLabel上显示属性。这不是默认行为。因此，我们欢迎你的到来。同时，您是否检查了生成的HTML输出中的元素以排除其中一个和另一个？@BalusC在生成的HTML中是这样的：ID=1，descripao=LIVRO
